Truck won't start with key

Asked by Jun 11, 2017 at 07:19 PM about the 1987 Ford F-150 XL Standard Cab 4WD LB

Question type: Maintenance & Repair

I've been having electrical issues with my '87 F150 V8 5.0.

Originally the battery was dying. Then I couldn't get it to start at all. I've put in a new
alternator and  a new solenoid  but it still won't start when I turned the key.

I got it to start up by jumping across the little start point and the positive input on the
solenoid with a screwdriver. I'm not sure what to do next.

When I turn the key, almost nothing happens at all. A few warning lights come on and I hear
one click somewhere in the engine, but I'm not sure where.

Also, the battery seems to be overcharging. The multimeter reads over 17 when the engine
is running.

Have you put in a new battery since changing the Alternator and Solenoid?

No, not since changing those two things.
